Aruba 6400 3000W Power Supply With C20 Inlet Adapter R0X36AABA

The Aruba 6400 R0X36AABA is a 3000W power supply with a C20 inlet adapter for Aruba 6400 switches, suited to network teams equipping or servicing compatible enterprise switching systems.

Recommended For

• Network teams maintaining an HPE Aruba Networking CX 6400 chassis that need a compatible R0X36A replacement or additional power supply; this model is specifically for the 6400, not a general-purpose server PSU.
• IT teams powering PoE-heavy CX 6400 deployments that need substantial chassis power for installed modules and connected devices; confirm the power budget against the chassis configuration and input voltage.
• Network infrastructure teams designing CX 6400 power redundancy, where the system’s power plan calls for multiple supplies and separate power circuits rather than relying on this unit alone.

Real-World Use Scenarios

• Replacing a failed power-supply module in an Aruba 6400 chassis: the R0X36A is hot-swappable, so the switch can remain connected to power while the module is changed, provided the chassis has adequate remaining power supplies for its load.
• Building power-supply redundancy for a campus or data-center switch: install multiple R0X36A units and configure a supported redundancy arrangement so a supply failure does not immediately remove all power to the chassis.
• Supporting a chassis with substantial PoE loads: add power-supply capacity when the installed line cards and powered devices require it, then check the switch’s power budget against the input voltage and chosen redundancy mode.
• Starting up or diagnosing a partially equipped chassis: a single PSU can power the fans and management cards for access and diagnostics, but it should not be treated as sufficient for full switch operation.
• Installing the PSU in a rack with an existing power distribution setup: use the matching C20 inlet adapter and confirm the PDU or power cord is suitable for the site’s voltage and connection before deployment.
